BUTTON-MAKING MACHINERY.

srEcIFIcATIoN forming part of Letters Patent No. 630,645, dated Augiist 8, 1899.

A puaiwmea March 13, 1899.

To all whom, it ma concern v Be it known that I, RUDOLPH H. BECK, a citizen of the United States,-residin'g at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Button-Making Machinery, of which the following is a specification.

My invention has relation to a button-making machine, andinsuclfcon'nection it 'relates more particularly to the construction and arrangement of the countersinking or turning tool and the drills, together with the mechanism 'fo'r operating said tool and drills. In a companion application filed the 10th day of March, A. D. 1899, under the Serial No. 708,507, the arrangement and construction of a preferred'form' of chucks for the machine, the' table carrying'said chucks, and the mechanism for operating the chucks and table have been illustrated, described, and claimed. Thepresentapplicationisdesigned to cover the preferred forms" of drilling and turning tools,which,although generally ad aptcentering or adjusting the tool'with respecti to the blank to be turned and mechanism for loweringthe tool into operative position and elevating it therefrom at the proper intervals of time, and, second, to provide two sets ofg drills, each drill beingof peculiar construction and arrangement, together with mechanism for adjusting and properly centering each set of drills and mechanism for elevatin g and lowering the sets of drills at the proper intervals of time.

To this end my invention consists, first, in providing in a button-makin g machine a countersinking or turnin g tool and its holder,'said tool being adapted to be quickly and easily inserted,.withdrawn,andadjusted in its holderv and said holder'b eing'adapted to be quickly and easily ad just'ed'in vertical and horizontalplanes to properly center the tool with regard ed for use with any type of chuck, are especially adapted for use with the chucks de-T Serial No. 708,826. (No model.)

to the blank. to be turned; second, in providing in a button-making machine, in connection with a countersinking' or turning tool holder and the drill-holders, mechanism for elevating and depressing the tool and drill 5 '5 holders at statedintervals of time and means for adjusting said mechanism, whereby the movement of the tool anddrills downward may be quickly and easily increased or decreased; third,in providing in a button-mak- 6o ing machine drills having the spindles arranged in sets of two in a drill-holder, said drill-spindles being adapted to be quickly and easily inserted, withdrawn, and adjusted in the holder and said holder being adapted to be quickly and easily adjusted in vertical and horizontal planes to properly center the drills with regard to the blank to be drilled, and, fourth, in providing in a button-making machine a drilling-tool comprising a hollow stem or spindle arranged obliquely in a holder and havinga removable lower portion of conical shape and adapted to receive the drill-point and means for adjusting and clamping said drill-point in said conical 'end portion of the spindle.

The nature and scope of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part thereof, in which.

Figure 1. is aside elevational view of a button-making machine embodying main features of my present invention. Fig. 2 is a top or plan View thereof. Fig. 3 is a side elevational view, enlarged,'of the countersinking or turning tool and its holder detached from the machine.

Fig. 9 is a front elevational view, enlarged, of one set of the drills and illustrating in vertical section the drill-holder and achuck and blank below the drill-points. Fig. 10 is a view, partly sectioned, taken at right angles to Fig. 9. Fig. 11 is a side elevational view of one set of drills and their holder detached from the machine. Fig. 12 is a rear-elevational view of the holder illustrated in Fig. 11. Fig. 13 is a front elevational view, enlarged, of the lower end ofonc of the drill-spindles. Fig. 1% isa vertical sectional View taken at right angles to Fig. 13. Figs. 15 and 16 are cross-sectional views taken, respectively, on the lines 15 15 and 16 16 of Fig. 14:; and Fig. 17 is a perspective view, enlarged, of the block clamping the drill-point in the end of the spindle.

Referring to the drawings, and particularly to Figs. 1 and 2 thereof, (t represents the bedplate of the machine, upon which are properly supported the necessary standards and the framework of the machine. In an end standard a. is supported the main power-shaft a which by preference is arranged vertically and carries at or near its upper end the two pulleys a and a, adapted, respectively, through suitable belting, to rotate the countersinking or turning tool and the two sets of drills. The shaft a also serves to operate the table a with an intermittent or step-by-step movement, so that the same may present the chucks a, arranged in series on said table, successively to the turning-tool and to each set of drills.

The construction and arrangement of the table a and of its chucks a", as well as the means for operating the same, form no part of the present invention, but form the subjectmatter of a companion application filed on the 10th day of March, A. D. 1899, under the Serial No. 708,507. For the proper understanding of the present invention a detailed description of the table and chucks is not deemed necessary. It is sufficient to state that each chuck a has two jaws a sliding beneath a plate a which is perforated to admit the blank A, and that these jaws a close down upon the periphery of the blank and clamp it in the chuck during the turning or countersinking of the blank and during the two successive drilling operations, which will be hereinafter described.

The pulley 01. operates, through the belt a", a pulley a keyed or otherwise secured to a vertically-arranged shaft b, which rotates in a suitable bearing 1), from which extends a bracket b having a slotted end secured to an upright orstandard of the machine. The bracket 1) serves as a brace for the shaft 1), and its slotted connection with a stationary part of the machine permits of an adjustment of the bearing b to compensate for the adjustment of the other bearing for the shaft Z), which, as hereinafter explained, also constitutes the adjustable support for diderent members of the holder for the countersinking-tool.

Referring now to Figs. 3 to 7, inclusive, the shaft 11 carries at its lower end a block (1, which rotates with the shaft and has on its under face a depending gage-plate d, which, by means of the bolt al working in the slot cl of the plate 61, maybe adj ustably secured to the block (1, so that it may be shifted toward or away from the center of the shaft b (which forms the axis of rotation of the block (Z) and locked in the required position. The lower edge (1 of this plate d forms an abutment for the cutting edge of the countersinking-tool e. The tool 0, as illustrated in Figs. 7 and 8, is adapted to be slipped into an obliquely-arranged slot 6 in a holding-block e and to be pressed upward against the upper face of said slot by a flat spring 6 The spring 6 thus insures the proper guiding of the tool a in the holding-block c and the plate (1 serves as a guide or stop to indicate that the tool 6 projects from the slot the required distance. The holding-block e is supported by the block (Z at an angle of approximately forty-five degrees to the axis of rotation of said block, and it is adjustable in the plane of its support by means of a dovetailed extension a", sliding in a corresponding slot in the block d. The holding-block a when shifted to its required position on the block cl is maintained in that position by the set-screws (1 The tool e when properly guided in the slot 6 is held therein by means of set-screws e or equivalent fastening means. The tool a is thus centered with respect to the blank by the plate d and by the shifting of its holder 6 upon the block d. The shaft 1) and the block d may also be centered with respect to the chuck by the following preferred means: The shaft 1) passes through two eyes f, projecting from a bracketf, which is adapted to slide on a longitudinally-arranged dovetail projection f of a block f, which block f is provided with a dovetail projection f adapted to slide in a horizontally-arranged complemental groove f of a slidef The arrangement is such that the shaft b is shifted by the movement of the bracket f longitudinally on the block f in a direction toward or away from the slide f and the shaft 1) and bracket f together are shifted on the slidef horizontally and in a direction parallel to the face of said slide. The shaft 1) may thus be shifted at any angle in planes parallel to its axis of rotation, the movement of the shaft being compensated for by moving the upper bearing Z1 and the bracket (1 which braces said bearing 1) by connecting it by a slotted connection I) with an immovable portion of the framework.

Returning now to the block d, which rotates with the shaft 1) and carries the tool-holder 6 it will be observed that the holding-block e is carried at one side of said block d, and hence if the block (.l were not properly halan'ced with respect to the shaft 12 there would be a tendency of the block d to rock during its rotation with the shaft b. To overcome this objection, a counterweight d is secured to the block d at a point diametrically opposite to the point at which the tool-holding block 6 is carried. This counterweight d 'is preferably adjustable on the block d, and hence is secured thereto by means of a bolt d passing through a slotted ear d of the counterweight, as clearlyillustrated in Fig. 4.

Referring to Fig. 5, when the shaft b is shifted by the bracket f away from the block f it is preferable that the connection between the bracket f and block f be strengthened, since the rotation of the shaft 1) will exert a torsional strain upon said bracket f. To strengthen or brace the connection of the bracket f with the block f a projection f is formed on the ears f of said bracket f, and this projection f is locked to a corresponding projection f 9 on the block f by an adjustable screw-bolt f It will be understood that the bracket f when properly shifted in the block f is locked to said block by means of setscrews f or similar means passing through the bracket f and impinging upon the dovetail portion of the block f and in the same manner the block f is locked to required position on the slide f by means of the setscrews f In the operation of the machine it is necessary at stated intervals of time to lower the tool 6 into operative position with regard to the blank A and after the tool has performed its function to elevate said tool into inoperative position with respect to the blank. The shaft 1) and the tool e having been properly centered, as hereinbefore described, the raising and lowering of said tool are accomplished by the following preferred mechanism.

Referring to Figs. 1 to 5, inclusive, the slide f is provided with 'a rack g, properly secured by screws or otherwise to the rear face of said slide, and in said rack g a pinion g is adapted to mesh. This pinion g is loosely supported upon a stud or pin g on one of the standards of the machine. Upon this stud g one end of a rock-arm g is also loosely supported. A bolt g adjustably secures the rock-arm g to the pinion g in a manner and for a purpose hereinafter described. The free end of the rock-arm g is provided with a roller 9 which by preference is adjustable in a slot of said rock-arm, and this roller 9 bears upon the periphery of a cam the rock-arm g being normally depressed by the spring g for this purpose. The cam q is carried by a shaft g to which motion is conveyed from the power-shaft a in any suitable manner. As the cam g rotates it will alternately raise and lower the rock-arm 9 which oscillates upon the stud g andthrough its connection with the pinion 9 serves to oscillate said pinion. The oscillation of the pinion g raises and lowers the rack g and causes the slide f to move up or down upon a stationary portion of the machine. The slide f 7 carries with it the bracket f, which through its ears f bears upward upon a collar 19 on the shaftb and downward upon the block (1. The movement of the slide f will therefore, through the bracket f, serve to elevate or depress the shaft b, and its block d,which carries the tool'e, will be lifted or depressed.

In the turning or countersinking of blanks of different thicknesses it is necessary to adjust the downward movement of the tool. To accomplish this, the connection of the rockarm g with the pinion g is made adjustable in the following manner: The bolt 9 passes through a curved slot g in the rock-arm g and the position it occupies with relation to the respective ends of the slot is regulated by means of the adjusting-screws 9 Referring now to Fig. 4, if it is found desirable to depress the shaft 1) and its tool 6 a greater distance than is normal the upper screw of the set-screws g is loosened, and the pinion g is turned upon its studg from left to right, thus depressing the rack g and slide f below its normal position, and hence lowering the shaft b and con ntersinking-tool toward the table and chucks. The rock-arm 9 upon being locked to the bolt 9 by advancing the lower screw of the set-screws 9 will now throw the pinion as heretofore; but of course the movement of the rack g and tool 6 will range between points lower than is normally the case, and the tool will be caused to enter the blank A more deeply. The rack g and slide f may be elevated to prevent the tool e from entering the blank A too far by a similar adjustment of the pinion g on its stud 9 but of course in an opposite direction. The blank A after being turned or countersunk is then presented to the mechanism for drilling the holes or eyes. Usually eachblank is provided with four eyes or holes, and hence in the drawings there is illustrated mechanism for drilling the four eyes, although it is to be understood that if required but two eyes may be drilled in each blank by the same machine by simply removing the drill-points from two of the drill-spindles.

In the present machine the drills are arranged in two sets, each set comprising two drills, and both sets are adapted to be brought into and out of operative position with respect to the blank. Inasmuch as the arrangement and operation of both sets of drills are the same, description of but one set is all that will be required.

Referring to Figs. 9 to 17, inclusive, each drill proper consists of a spindle m, having at its upper end a pulley m and at its lower ,end a removable conical portion m in which the drill-points m are adapted to be securely clamped. The spindle m and its conical end portion m are both hollow, the spindle m preferably for onlya portion of its length, to receive the upper portion of the drill-points m The conical portion m is provided with a vertically-arranged slot m the lower end of which is curved, as at m and this slot extends from the face to the interior opening in the conical end m In this slot 911. is adapted to be slid a bar on, having one face grooved, as at m to fit closely down upon the drill-point m This bar m is clamped down upon the drill-point m by means of a set-screw m or similar device, as illustrated in Figs. 14 and 16. The curved lower end m of the slot m permits one end of the bar m to be lifted outward to release the drillpoint when the set-screw m is released. In drills of this character it is essential in drilling two or more holes in very small blanks that the drill-points be brought very closely together. This is accomplished in the following manner: Each spindle m of a set is guided obliquelyin a holdern in such a manner that the drill-spindles converge until they almost meet at the points where their conical ends m are screwed into the spindle proper. (See Fig. 9.) The ends 'm being conical, the drill -points m are prevented from crossing, but are guided into substantially parallel relationship, while closely approaching each other. The conical ends m being readily removable from the spindles m, any accident to a drill-point m can be remedied by unscrewing the conical end and removing both end and drill-point and replacing the same with a new end and a new drillpoint without disturbing the spindles proper. The holder n for each set of spindles is adjustable much in the same manner as is the bracket f, which guides the shaft 1) of the counter-sinking or turning tool ethat is to say, the holder n slides on a block n toward or away from the slide 12 and the block n is movable on the slide 12 in a direction parallel with said slide 72 and at right angles to the movement of the holder on the block a. As illustrated in Figs. 1 and 2, the slide n is common to both sets of drills and is elevated and depressed in the same manner as is the slide f of the tool ethat is to say, a pinion 71 operates a rack a, secured to the slide, and this pinion n is operated by a rock-arm n by means of a cam a on the shaft 9 in the same manner as the heretofore-described movement of the rock-arm g cam 9 and shaft 9 The cams g and a and the rockarms 9 and n are arranged so that the sets of drills and the tool 6 are simultaneously elevated and depressed. The throw of the rock-arm n is adjusted in the same manner as is the throw of the rock-arm 9 but independently thereof. Where the blank is to be drilled by two sets of drills, as illustrated in Fig. 2, it sometimes happens that the drillpoints of one set will not be adjusted properly, so as to drill holes in the blank at right angles to the holes drilled by the points of the other set. This adjustment of the angular position of the drill-points without separating or spreading the drills, however, may be obtained, as illustrated in Fig. 9, by swiveling the holder 11 in the bracket 7t and using a set-screw n to fix the holder in the bracket after the holder and drills have been turned to required position.
